Bought them from another guy (never ran) and highly doubt they've been ported... Think my best bet would be to take them to a machine shop so they can check them out and take it from there ? Only spent $300 on them thought it was a steal for a new set of aluminum heads.

As long as you don't mind dropping 750-1000 at a machine shop those heads can be made fairly decent.

As far as cam goes, I would NOT use that 292 cam, if you already have it then go ahead and use it but its far from ideal. If you want a race cam get a flat tappet solid cam with face oiling lifters, if you want a low maintenance cam then knock about 15 degrees duration off the one you selected. Better deal yet would be a solid roller cam, but most people can't afford that. a decent solid flat tappet cam with good lifters should run you under $300.
